BOOT OR/SHOE.

SPECIFICATION forming part of Letters Patent No. 310,159, dated December30, 188

Application filed November 3, 1884. (No model.) I v To all whom, it mayconcern.-

Be it known that I, ANDREW J. WILBUR, of Boston, county of Suffolk,State of Massachusetts, have invented an Improvement in 5 Boots orShoes, of which thefollowing description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention, 1 elating to boots and shoes, is intended as animprovement on Letters Patent No. 305,120, dated Septemberlti,188$,wherein an inner sole, slitted so as to leave a marginal weltor border to receive the stitches or fastenings, was employed toincrease the flexibility of the boot or shoe. In the said patent, inorder to prevent the marginal welt or border of the inner sole frombeing drawn away from the main body thereof,'and thus prevent tightlasting, it was necessary to cut the upper of such size or fullness asto lap about the last and sufficiently beyond the marginal welt orborder to enable the lasting-tacks to be driven into the upper and intothe main body of the inner sole insidethe welt or border, thus addingmaterially to the cost of the boot or shoe. To obviate the necessity ofmaking the upper as full or wide as stated, and yet gain the advantageof flexibility due to the employment of a slitted inner sole, I attachto or provide the under side of the latter with a supple mentary innersole, which serves to re-enforce the slitted inner sole and enable theupper, as it is lasted, to be connected to the margiual welt or borderof the inner sole; and it 3 5 is in this particular feature that myinvention essentially consists. The supplementary sole employed, made ofnon-elastic material, preferably textile fabric, is cut of such shape asto cover the slits in the inner sole at its under 4,0 side.

Figure 1 shows a cross-sectionof ashoe made in accordance with thisinvention; Fig. 2, a bottom view of the inner sole; Fig. 3, amodiiieation to be referred to. +5 The inner sole, (1, cut to the propershape, is slit at a a from at or near the toe part to the shank, or asfar back as may be desired, thus forming a connected marginal welt orborder, to? a", which receives the stitches or fast;

enings to be employed. Thisinner sole, a, slit as described, hasattached to its under side,

by cement or otherwise, a supplementary sole,

b, preferably made of textile material or inexpensive leather, and ofthe same size as the inner sole, a. 5

In the preparation of the shoe the inner sole,

0, with the supplementary sole b attached thereto, is laid upon thelast, the inner sole, a,

resting against the bottom thereof. The up per 0, of usual size andmaterial, is then drawn 50 over the last and secured by tacks orfastenings, which penetrate the upper and the sup plementary sole andenter the marginal welt or border a a the uncut supplementary sole beingnon-elastic to thus resist the strain of 6 the upper and keep themarginal welt from being pulled away from the main portion of the innersolo. The outer sole, S, suitably channeled, is then applied by suitablelastingtacks, and stitches or fastenings are then made to extend throughthe said outer sole, upper, supplementary sole, and the marginal welt orborder of the inner sole, thus permanently uniting all the partstogether.

A fillingsole maybe interposed between the 7 5 supplementary and outersole, as at d; but, preferably, in the manufacture of fine quality shoesI reduce the thickness of the marginal welt, as shown in Fig. 3, leavingthe main body sufficiently thick to fill this space, and in such shoes Ipreferably also employ a sock-sole.

It will be seen that the stitches or fastenings unite the upper to theslitted inner sole at its toe and heel portions direct, while betweenthese two points it is united to the marginal welt or border, leavingthe main body of the inner sole free to conform to the action of thefoot of the wearer in walking,'and the nonelastic supplementary solebeing attached to the slitted inner sole firmly any strain of the 0upper on the marginal welt or border which tends to draw the same fromthe main body of the inner sole is resisted, whereas in the patentreferred to, to avoid strain on the welt, it was necessary to secure theupper directly to 9 5 the main body of the inner sole.

In Fig. 2 I have shown the marginal welt or border at each edge of thesole connected with the main body of the inner sole at but two I orborder of the inner sole and an outer sole, points; but the same may beconnected at sevall permanently united by stitches or fasten- 15 eralpoints, or as shown in the patent referred ings extended through theouter sole; upper, to or, if desired, the slits'a, instead of beingsupplementary sole, and marginal welt or bora made entirely through theinner sole, may be der, all substantially as described.
